TABULATING MECHANISNI FOR TYPE-WRITERS.

SPECIFICATION forming part of Letters Patent No.' 609,517, dated August-23, 1898.

Application tiled June 15, 1897.

To @ZZ whom t may concern,.-

Be it known that I, EDWARD J. MANNING, a resident of the city, county, and State of New York, have invented certain new and useful Improvements in Tabulating Mechanism for Type-Vriters, of which the following is a specification.

My invention relates to what is known as tabulating mechanism for type-writers-jthat is to say, mechanism particularly available for writing bills, invoices, statements of account, dto., wherein tabulation of the work Written is necessary and wherein the touching of a certain key or lever allows the carriage to travel across the machine from right to left and causes the carriage to be automatically stopped ata certain predetermined point, when the writing may be continued, as before. In machines of this character heretofore devised a depression of the tabulating-key would result in the carriage being rapidly propelled by its spring across the machine, and the sudden stopping of the carriage by the adjustable stop would result in jarring the entire machine and render the parts liable to become broken.

The object of my invention is to overcome the difficulties heretofore found in machines of the character specified and to provide a type writer with tabulating mechanism wherein the speed at which the carriage travels across the machine is under the control of the operator, so that the jar upon the parts may be overcome and the liability of damage decreased.

In the accompanying drawings, wherein like reference characters indicate corresponding parts in all the views, Figure 1 is avertical transverse section of Fig. 2, showing sufficient number of parts of a type-writer to illustrate my invention. Fig. 2 is a rear view of the same. Fig. 3 is a top view of a portion of the same with parts broken away. Figs. 4 and 5 are enlarged detail perspective and bottom views, respectively, of the tabulatingstop and its carrying-frame.

In the drawings, A represents the framing of a type-writer, in which various parts of the device are mounted. Upon the framing A is carried a suitable carriage B, which is adapted to traverse the framing and is provided with Serial No. 640,843. (No modal.)

suitable feeding mechanism for feeding the carriage o ne space at a time in the usual manner. In the present instance this feeding mechanism is shown to comprise a universal bar a, against which the heel l? of a` type-bar C is adapted to abut before the impact of a type against the paper on the paperplaten D. This universal bar ci is connected, as` by means of the links or connecting-pieces c, with suitable spring-pressed links d, which normally maintain the universal bar a in the path of a type-bar C in its oscillation to the printing-point. Upon the links c or suitable portions carried thereby are the feeddogs ef, which engage alternately a rack g, carried by and traveling with the carriage B. The feed-dog c is made longitudinally movable by means of the slot 7L and is normally maintained in the position illustrated in Fig. 2 by means of a coiled springt'. Both of these feed-dogs are adapted toy be vibrated in and out of contact with the rack g around their pivot j, and in order that this may be accomplished a pin k is provided, which is carried by a piece Z, which connects with the feed-dog f, but in a movement downward causes a corresponding movement of both feed-dogs to cause them to be disengaged from the rack g. A rock-shaft E is pivoted at the rear of the machine, which rock-shaft is normally maintained in the position illustrated in Fig. l by a coiled spring which surrounds the shaft. The right-hand end of this rockshaft is provided with ratchet-teeth mi, which are engaged by teeth f* on an adjustable tabulating-stop F, which is normally maintained in engagement with the teeth m by a spring n, the tabulating-stop F being pivoted in a frame G, which is carried by the rock-shaft E and adapted to slide thereon. Projecting upwardly from the rock-shaft E is a brake I'I, which is adapted to contact with the framing of the carriage B when the rock-shaft has been vibrated in the direction of the arrow, Fig. 1. At the point where the brake H bears against the carriage B said carriage is provided with a strip I of leather or other suitable material to prevent a scratching noise and to fr cilitate the action of the brake. It is ofcourse obvious that this strip of leather may be carried upon the brake,but I prefer to place it IOO upon the carriage in the manner shown. The upper portion of the brake I-I is provided with a scale which corresponds to a portion of the ordinary scale upon the type-writer, which is used to determine the position of the paperplaten with relation to the printing-point. Cooperating with the scale on the brake H is a pointer o, carried by the adjustable tabulating-stop F. A handle p is likewise connected to the adjustable tabulating-stop for the purpose of disengaging teeth fi on said stop from the rack m and setting the stop at any point it is desired to stop the carriage for tabulating work, the scale on the brake H facilitating the determination of location of the tabulating-stop. A spring o* tends to normally maintain the teeth on the stop in engagement with the rack m. From the under side of the rock-shaft E projects a finger q, which bears against the pin 7c, carried by the feed-dogs of the feeding mechanism, so that when the rock-shaft is vibrated in the direction of the arrow in Fig. l the feed-dogs will be thrown out of engagement with thev oted link r is connected to a depending arm s of the rock-shaft E and is adapted to be vibrated by an arm t, connected with a tabulating-key .I which projects to the front of the machine and is under the control of the operator. This tabulating -key .I is so arranged that the harder it is depressed the greater will be the pressure exerted upon the carriage by the brake I-I. By this arrangement it will be seen that the ordinary carriage-feeding mechanism may be operated without in any way affecting the operation of the tabulating mechanism, since the pin k can be vibrated backward and forward with the feed-dogs without moving the finger q, which cooperates therewith to throw the dogs out of engagement. However, when it is ldesired to operate the tabulating mechanism it is merely necessary to depress the tabulatingkey J, when the rock-shaft E will be vibrated in the direction of the arrow, Fig. l, thereby causing the linger q, connected therewith, to force the feed-dogs c f out of engagement with the feed-rack g, and will simultaneously apply the brake H to the carriage, and will at the same time vibrate the adjustable tabulating-stop F into the path of the abutment u upon the carriage, and thereby automatically stop the carriage at any predetermined point. When the iinger is released from the tabulating-key, the parts resume their normal position, and the operator may continue to write as before. I have stated that a depression of the tabulating-key J will result in automatically applying the brake at the same time that the feeding mechanism is disengaged and the tabulating-stop interposed in the path of the abutment on the carriage. This is true only when the tabulating-key is depressed and maintained down with some considerable pressure, since a very slight depression of the tabulating-key will release the feeding mechanism andinterpose the tabulating-stop into the path of the abutment on the carriage, but will not be sufficient to force the brake H into contact with the carriage, so that if it is desired to allow the carriage to be propelled by the spring with considerable force across the machine it can be accomplished. The greater the pressure eX- erted upon the tabulating-key the greater will be the force applied to the brake, so that it will be seen that the carriage can be allowed to travel at any rate of speed desired.

' While I have shown and described one form of mechanism for carrying out my invention, I would have it understood that I do not wish to limit myself to this particular construction, inasmuch as I am aware that various modifications may be made without departing from the spirit of my invention, which consists, broadly, in providing tabulating mechanism wherein the speed of the carriage is maintained under control of the operator when the tabulating mechanism is being put in operation.

WhatI claim, and desire to secure by Letters Patent, is-

1. In a type-writer, the combination of a movable carriage, tabulating mechanism for causing said carriage to move any desired number of spaces according to adjustment and means for controlling the speed of said carriage in its movement in the direction of its feed, and mechanism for throwing the controlling means into and out of operation at will.
